Congressional Republicans on Thursday swore they weren't done trying to repeal Obamacare after President Trump signed an executive order borne out of frustration over Congress' inability to eliminate the law.

Trump signed an order Thursday aimed at loosening the healthcare law's insurance regulations and added that he will push Congress to repeal the law.

"I will continue to push for our legislation which will return healthcare power and decision-making to patients and states," Sen. Lindsey Graham, R-S.C., said after Trump signed the order Thursday.

The House passed an Obamacare repeal bill in May, but the Senate failed to pass three Obamacare repeal bills over the summer.

The GOP's failure to pass the Graham-Cassidy overhaul bill last month put Obamacare repeal on ice for now.
